The correct statements are B and D.

Explicar

## Step 1<br />The problem involves understanding the principles of gravity and motion. The scenario is set in a vacuum, which means there is no air resistance. <br /><br />## Step 2<br />Statement A suggests that the soccer ball will reach the ground faster than the car. This is incorrect because, in a vacuum, all objects fall at the same rate regardless of their mass. This is a fundamental principle of physics known as the equivalence principle, which was famously demonstrated by Galileo.<br /><br />## Step 3<br />Statement B suggests that the soccer ball and the car experience the same gravitational force. This is correct. The gravitational force experienced by an object is directly proportional to its mass. However, in a vacuum, where there is no air resistance, all objects fall at the same rate, meaning they experience the same gravitational acceleration.<br /><br />## Step 4<br />Statement C suggests that the car will reach the ground faster than the soccer ball. This is incorrect for the same reasons as statement A.<br /><br />## Step 5<br />Statement D suggests that the soccer ball and the car experience the same acceleration due to gravity. This is correct. In a vacuum, all objects fall at the same rate, meaning they experience the same gravitational acceleration.<br /><br />## Step 6<br />Statement E suggests that the gravitational force each object experiences is dependent on mass. This is correct. The gravitational force experienced by an object is directly proportional to its mass.
